Objects and Methods
Confluence
This object models a confluence of water.
General Slots

Information:  
I/O: Optional; can input, set by propagation across a link, or calculated
Inflow2
Type: AggSeriesSlot
Units: FLOW
Description: flow from the other side into the confluence
Information:  
I/O: Optional; can be input, set by propagation across a link, or calculated
Outflow
Type: AggSeriesSlot
Units: FLOW
Description: flow out of the confluence
Information:  
I/O: Optional; can be input, set by propagation across a link, or calculated
User Methods
Confluence Solution Direction
This method category is used to specify the direction the Confluence solves (downstream given the two inflows or upstream given the outflow and one inflow). For basic Simulation runs this does not make a difference and the default method should remain selected. However, in Rulebased Simulation the user may need to limit the Confluence to downstream solution only.
* Solve Upstream or Downstream
This is the default method and should remain selected for basic Simulation. There are no slots or calculations specifically associated with this method. It simply allows all dispatch methods to be active.
* Solve Downstream Only
This method may need to be selected in Rulebased Simulations where the Confluence can solve in the downstream direction only. When this method is selected, only the solveOutflow dispatch method is selected.
Dispatch Methods
This object solves for inflow1, inflow2, or outflow, when the other two are known. If the Solve Upstream or Downstream method is selected, then all dispatch methods are active. However, if Solve Downstream Only is selected, then only the solveOutflow method is active.
* solveOutflow
Solves for outflow.
